Probably not directly that way. Probably you'd be able to do it through
all the mutant SQL character classing stuff when that's implemented.

I don't know much about the locale stuff, but I'd guess that right now
if you could find a locale which treated those characters as equivalent,
you'd probably be able to get truly insensitive searches. (I don't know
if that's even possible to specify in locales, but I'm sure someone who
knows will pipe up with an answer now :) )
